Statistician : A financial magazine claimed that its survey of its subscribers showed that North Americans are more concerned about their personal finances than about politics. One question was: “Which do you think about more: politics or the joy of earning money?” This question is clearly biased. Also, the readers of the magazine are a self-selecting sample. Thus, there is reason to be skeptical about the conclusion drawn in the magazine’s survey.

Each of the following, if true, would strengthen the statistician’s argument EXCEPT:

A) The credibility of the magazine has been called into question on a number of occasions.B) The conclusions drawn in most magazine surveys have eventually been disproved.C) Other surveys suggest that North Americans are just as concerned about politics as they are about finances.D) There is reason to be skeptical about the results of surveys that are biased and unrepresentative.E) Other surveys suggest that North Americans are concerned not only with politics and finances, but also with social issues.

This post receivedKUDOS

This I guess has been taken from the Powerscore CR bible. The explanation given in the same is quite verbose and clearAnyways I will try putting it in my own words.The main conclusion here is: "There is a reason to be skeptical about the conclusion drawn by the magazine's survey"

A and B obviously strengthen it so are eliminatedC can be reworded as "North americans are as much concerned about finances as politics if not less", which again tends to strengthen the premises from which the conclusion is drawnD -> is more or less like the last line of the stimuliE -> This answer clearly doesnt impact the conclusion, since it speaks about a new topic i.e social issues which wasn't a part of the stimuli...

Each of the following, if true, would strengthen the statistician’s argument EXCEPT:

A) The credibility of the magazine has been called into question on a number of occasions...strengthen's the argument.B) The conclusions drawn in most magazine surveys have eventually been disproved......strengthen's the argument.C) Other surveys suggest that North Americans are just as concerned about politics as they are about finances.....strengthen's the argument.D) There is reason to be skeptical about the results of surveys that are biased and unrepresentative.....as the sample is self selecting ....strengthen's the argument.E) Other surveys suggest that North Americans are concerned not only with politics and finances, but also with social issues.....does not strengthen....hence correct

can someone please explain how is OA E?Mag X survey says something which author does not agree to and is skeptical.Other survey too denies the fact and infact gives new perspective of people - choice E.

Then in fact choice E also strengthen author's claim that Mag X survey is incorrect. Isnt it also a strengthener ?

The conclusion is 'there is reason to be skeptical about the conclusion drawn in the magazine’s survey'. The survey says that people are more concerned about personal finances than politics. So a strengthener would either reinstate what the survey results are or give reasons that survey is credible. Now the Choice E talks about social issues which is not related to the argument. So it would not strengthen the argument in any way.

I could say this question is not of a proper type... Let me explain why...

The question is we have to find an option that weakens or has not effect on Statistician's conclusion..

A) The credibility of the magazine has been called into question on a number of occasions.Many past events can't necessarily demand the present or future to be the same.. You can't surely say that you will get only 720 again in today's GMAT, as you have scored same 720 in past GMAT tests, could you? so we cant say it is strengthening the argument..

B) The conclusions drawn in most magazine surveys have eventually been disproved.Most of the magazines? does it include this financial magazine as well or not? Even so you can't underestimate the credibility of this statistics... so we cant say it is strengthening the argument..

C) Other surveys suggest that North Americans are just as concerned about politics as they are about finances.It states that Politics=finance in consideration, if so this strengthens the author's argument.. But which finance? Personal finance in question, or nation finance?

D) There is reason to be skeptical about the results of surveys that are biased and unrepresentative.If true as per the question, this result might have problem.. It strengthens the author's arg...

E) Other surveys suggest that North Americans are concerned not only with politics and finances, but also with social issues.This option has been picked as answer.. But how you could say it weakens or OOS? please read the "North Americans are concerned not only with politics and finances" portion in the option... It says that people are concerned about politics, finances and social issues... they place a race between politics and finances here as well on people's mind... How could it be OOS just because social issues are added? it is obviously strenthening as well...

I feel A or B one of them could be a right option... Share your valuable suggesstions as well...

I rephrase the conclusion as follows:1)The question is not well asked2)Americans are as much or more concerned about politics

Now I go to the answersAnswers A, B and D all say that the question is not well asked (1) (credibility issues, biased results and wrong conlusions)Answer C falls into category (2) and attacks the magazine's conlusion

Answer E is close to my statement (2) but it doesn't tell what americans are most concerned about politics/finance? So it doesn't do anything. Plus social issues is just out of scope. So answer E

Each of the following, if true, would strengthen the statistician’s argument EXCEPT:

The Except Questions in Assumption Based Stimuli will either be irrelavant to the question or do the opposite.

In Strengthen weaken it will either Weaken or Be Irrelevant..

Analyzing the Stimuli :-

Conclusion :- The survey is not accurate

Evidence :- The Question is biased and the Replies are not representative of the the population

Assumption :- The survey is not representative of the conclusion

A) The credibility of the magazine has been called into question on a number of occasions. :- It strengthensB) The conclusions drawn in most magazine surveys have eventually been disproved. StrengthensC) Other surveys suggest that North Americans are just as concerned about politics as they are about finances.It provides the support to the conclusion with an external evidenceD) There is reason to be skeptical about the results of surveys that are biased and unrepresentative. This is a mere paraphrase of our assumptionE) Other surveys suggest that North Americans are concerned not only with politics and finances, but also with social issues. Bingo - Irrelevant
